Can I adjust the PSI on my 2 gallon compressor

by Sherry Webb
(London, ON Canada)

Is it possible to adjust the PSI on my 2 gallon mastercraft compressor model #058-1289-2 down to between 45 and 65 PSI. I bought this little compressor in order to use my Air Eraser which has a maximum PSI of 65. When I bought this compressor I was under the impression that the PSI adjustable but if it is I have NO idea how to do it. The Instruction manual isn't much help. If you have any insights, I would be so grateful.

I solved my issues with the compressor
by: Sherry Webb

After doing a bit more research, reading everything I could find on this site and seeing that there was another compressor on sale the next day for a few dollars more.....I packed up the 12 gallon without the second regulator gauge took it back to Canadian Tire and purchased the 3 gallon that definitely has the pressure regulator gauge and adjustment knob. Thank you so much...this site was a great help

Adjust the PSI
by: Bill

In the absence of a regulator with the compressor, one can be added anywhere downstream of the discharge coupler if desired.

(While I chuckled about the political reference, it has been expurgated as this site is not a political forum - B.)

Sherry and Bill:

Incredibly, the machine shown on the Canadian Tire site has no regulator.

The manual, however, shows one.

The quick check is that the one shows two gauges, and the CT only has one gauge.

You should be able to, Sherry.

See the page on Regulators on this website, and then check and see if your air compressor has one.

If it does, use it to reduce the pressure to the level you wish to flow down the air line. If your compressor does not have a regulator, in order to accomplish your goal, you will have to have an air regulator in the line somewhere before your air eraser.
